Now, SAA members have voted to change the society’s bylaws to prevent similar events. Starting on 20 November, the SAA board may bar people found to have committed sexual harassment or other misconduct from society events, as well as revoke their membership. But a bylaws amendment some felt represented a stronger stand against sexual harassment did not pass. > Sexual harassment came to fore at this year’s SAA annual meeting, held in April in Albuquerque, New Mexico, when David Yesner, an archaeologist who had recently been found guilty of harassment by the University of Alaska in Anchorage and banned from campus, registered onsite for the meeting and was allowed to attend. Some of Yesner’s accusers were also at the meeting and his presence made them feel unsafe. They reported the situation to SAA, but the organization was caught off guard, unsure how to respond to harassment that had occurred before the meeting at a different institution. SAA was slow to remove Yesner and protect his accusers, leading to widespread outrage among members. At the time, Sherry Marts, a consultant in Washington, D.C., who advises nonprofits on how to address sexual harassment at meetings, called the society’s response “a worst-case scenario.”
